Enum CloseResponse 

pub enum CloseResponse {
    Close,
    Veto,
}

Verdict returned by a window’s close guard when the user (or the app) asks to close the window.

The guard runs before the window’s tree is torn down. Returning Veto cancels that one close attempt and leaves the window open — the idiomatic place to pop a “you have unsaved changes” confirmation, then re-issue the close via EventContext::close_window_forced once the user confirms.

Variants

Close

Proceed with closing the window.

Veto

Cancel this close attempt; the window stays open.
